Need to access /replace hot water shut off vacuum valve.

[Hoosier Mark]

Hi.....what is the best way to access & change this vacuum valve which sits on top of the heater box in the dash? I hope the easiest way is to remove the map pocket panel? How is this accomplished? Anything to watch out for? I own a 1977. Thanks very much.

Hi Mark,

I'm not sure how the interior of a 77 goes together, all I can share is what I encountered on my 71.

Maybe this update from my project will be of help but chances are they changed quite a bit between 71 and 77.

Good luck!
